Abstract
A gas/solid separation system that can be applied to any type of FCC unit regenerators, consists of a device for separating solid particles contained in a gas stream coming from the regeneration zone of a fluid catalytic cracking (FCC) unit bounded by an inner envelope () of cylindrical shape centered about the vertical axis of the regeneration zone, and an outer envelope () that has one approximately horizontal wall (), followed by one curvilinear wall (), and one approximately vertical wall (), the set of said walls () covering the inner envelope () and forming a set of separation chambers () radially distributed around the inner envelope () in which the gas/solid suspension to be separated circulates. This system makes it possible to obtain, at the same time, very good separation efficiency while minimizing the pressure drop and only requiring a single downstream cyclone stage.
